I recently got the Razer Nari Wireless headset. When I got it all setup the sound was very hollow sounding. I kept trying to mess with the settings to get it to sound right but nothing worked. I did a bunch of research to find a lot of other people having similar issues. I ended up returning the headset and opted to get the Sennheiser 373D headset. When I got the headset setup I went to test it and the same thing happened. The sound was very hollow and had no bass. I also noticed the 7.1 surround sound was not working. All the channels were able to output sound but it was in a the exact same sounds coming from each side. I followed the steps in the manual on how to set the headset up too.
